Climate change is becoming an increasingly urgent and complex global issue, affecting various aspects of life including global security. As Earth’s temperature rises, the impacts are felt in the form of extreme weather, changes in rain patterns, and rising sea levels. This phenomenon creates challenges for countries around the world, especially those with limited resources. One of the most significant impacts of climate change is the increased frequency of natural disasters, such as floods, droughts and storms. This disaster not only damaged infrastructure, but also directly threatened food security. Countries that depend on agriculture, such as those in Sub-Saharan Africa, are very vulnerable to crop failure due to uncertain climate conditions. This could lead to mass starvation and increase the potential for conflict over increasingly scarce resources. Climate change is also driving forced migration. According to a UNHCR report, more than 20 million people are estimated to have become climate refugees, and this number is likely to increase. This migration could create tensions in an already unstable region. For example, in Southeast Asia, population movements due to rising sea levels can trigger conflicts between local residents and migrants. This exacerbates insecurity in a region already facing socio-political challenges. The clean water crisis is another issue caused by climate change. As temperatures increase, water evaporation accelerates and fresh water sources become increasingly depleted. Countries in conflict such as Iraq and Syria have experienced strife exacerbated by a shortage of water resources. Competition for access to clean water can create conditions for instability and the potential for war. The global economy is also threatened by the impacts of climate change. Rising losses from natural disasters force countries to spend larger budgets on recovery, diverting funds from security investments. On the other hand, the transition to renewable energy to reduce greenhouse gas emissions could trigger tensions between countries producing fossil energy and those switching to cleaner alternatives. Climate change affects international safety and can disrupt cooperation between countries. In this context, some countries may seek to obtain needed resources by aggressive means or by imposing territorial dominance. For example, rising temperatures and melting ice in the Arctic create new access to shipping routes and oil and gas resources, which can trigger territorial claims and conflict between countries. Considering these implications, it is important to view climate change as not only an environmental problem, but also as a global security issue that requires international collaboration. Mitigating the impacts of climate change and adaptation efforts must be integrated into every foreign policy strategy, in order to achieve better world security and stability.
